Examples of within-subject surface and volume extraction. Examples of the extracted cerebral cortex surface and cerebellum boundaries are shown for 3 typical subjects within their native space. The green line shows the estimate edge of the cerebellum tailored to each individual subject's T1-weighted image to illustrate deviations in the T2* images. Imperfections are apparent in the BOLD data, especially in regions prone to susceptibility artifact (e.g., inferior temporal cortex).
